Emobi and HeyCharge roll out retrofit to bring offline EV chargers into large North American roaming network

Emobi and HeyCharge have formed a technical partnership to retrofit legacy EV chargers so they can participate in a major North American roaming and authentication layer. The retrofit brings local, hardware-enabled communications to chargers that experience poor internet connectivity, allowing them to operate reliably in environments such as underground garages and dense urban buildings. Once updated, these chargers can join Emobi’s interoperability layer and become accessible to automaker interfaces, fleet management platforms, and consumer charging apps, while also supporting Emobi’s cloud-based authentication workflow that requires no new customer-facing hardware. The joint solution aims to reduce installation complexity and ongoing operating costs by removing dependence on constant internet connectivity and by minimizing the need for specialized labor during deployment. For operators and property managers, the conversion offers predictable session tracking, energy-based billing, and centralized settlement processes that are otherwise difficult to standardize across fragmented charging networks. Fleets and automakers benefit from a more uniform authentication and data-exchange surface, which simplifies integration and improves uptime for distributed charging assets. Technically, the approach pairs local tokenized security and offline-capable communications with an API-driven roaming hub, creating a bridge between constrained edge devices and cloud orchestration services. That architecture mitigates a common single-point failure—intermittent connectivity—while preserving enterprise-grade features such as usage accounting and real-time availability reporting. Near-term challenges will include scaling retrofit deployments across heterogeneous charger inventories and coordinating firmware and backend compatibility between site hosts and networked platforms. There is also an operational risk vector around ensuring consistent token lifecycle management and secure key provisioning at scale, which both parties say their technologies address but which will require careful validation in live networks. Strategically, the partnership reduces fragmentation in access and billing for charging infrastructure and accelerates the practical electrification of sites that were previously uneconomic to upgrade. If widely adopted, the retrofit could materially raise effective charger availability for fleets and consumers without requiring wholesale hardware replacement, shifting investment from capex-heavy refresh cycles to targeted edge upgrades.
